But I can't reproduce the problem that way. Just after booting I run alternatively /opt/dvb-apps/bin/szap -a 0 -r "CCTV 4" /opt/dvb-apps/bin/azap -a 1 -r "57.1" and then I run them concurrently and finally I disconnect the USB tuner and replug and retry the 'azap' I did not get any crash yet. So there is likely some other "environmental" condition that is relevant. I will continue using 2.6.32.7. Whenever I meet the problem I will take note of the environment and try to reproduce the same environment with other versions of the kernel.
